Force lvs creation is required

Forcing the creation of the lvs is required otherwise we are facing this issue:

This is basically the change (-y):

createLV()
{
  SIZE=${1}
  VG=${2}
  LAST_LV=$(lvs autopart --no-headings --separator , 2>/dev/null | awk -F "," '{print $1}' | awk -F "lv_" '{print $2}' | sort -n | tail -1)
  NEW_LV=$((LAST_LV + 1))
  lvcreate -L ${SIZE}G --name lv_${NEW_LV} ${VG} -y
}
